HUB FOR AUTOMOBILE-WHEELS.

Specification of Letters Patent.

Patented March 23, 1909.

To all whom t may concern.'

Be it known that I, ALFRED A. DE Mans, a citizen of the' United States, resident oli Lakewood, county of Cuyahoga, and State of Ohio, have invented a' new and useful Improvement` in Hubs for Automobile- Wheels, of which the following is a specification, the prin'ciple of the invention being vherein explained andthe best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

My invention relates to automobile wheels and particularly to the hubs thereof and has for its object the provision of a hub of such construction' that, when it is necessary to remove or replace an automobile tire, the same may be done much more easily and quickly than is possible with present wheelconstructions with which I am acquainted, by removing 4or replacing the greater art ot' the wheel, including a portion of the ub.

Said invention consists of means hereinafter fully described and specifically set forth in the claim.

The annexed drawing and the following description set forth in detail certain mechthe invention may be used.

anism embodying the invention, such disclosed means constltuting but one of var1ous mechanical forms 1n which the pnmclple of' In said annexed drawing: the figure represents a partial axial section and a partial elevation of my improved wheel-hub.

In the construction illustrated and showing one way of carrying out the spirit of my invention, the hub comprises essentially an outer member A and an inner` member B. Said outer member A comprises the main portiona and the inner clamping ring a forming between them the groove afE adapted to receive and retain the spoke-tenons (not shown). Said portion a is formed with the inner groove a. The inner ymember B is formed with the aperture b designed for the reception ofthe axle-box and is provided with a spline b adapted to be received by the groove-a.3 to non-rotatably secure together the members A and B. The outer surface of the member B is provided with a thread b2 -adaptedto receive an internally-threaded B are provided with complementary tapering surfaces, the member A having such an |inner surface and the member B such an i outer surface. The use olI my improved hub is as follows: hWhen it is desired to remove or replace a tire, the same is not removed l'rom the wheel-rim, i but the ring C is unserewed lrom the thread b2 and the outer member Aol' the hub driven oil the inner member B, the rim, spokes, tire, t'clly and connected parts ol' the wheel being thus all removed together, theI tapering surl'aces d (l rendering such removal an easy operation. Another wheel, an extra one or more ol' which it is proposed that an autol mobilist should carry in lieu ol' the tire alonel can then be driven over the member B' and the ring (l replaced. Such operation, it will be readily apparent, is much more easily and quickly accomplishwl thanwould be the rcmoval of a tire from the .vheelfrim and the replacement ol' the same by another tire. l

The use ol' my invention will be most convenient, ol' course, when the automobilist is upon the road, and, consequently, upon such an occasion more than any other desires to quickly replace a damaged tire. The. latter can be removed l'rom the rim and repaired or replaced by another when the automobilist returns to the garage or any other place and at such a time as is most convenient for him. Having thus described my invention in de tail, that which I particularly point out and distinctly claim is:

A hub l'or automobile wheels, comprising an inncrfmember having a tapering outer surface, and screw threaded at one end, and adapted to vreceive an axle-box, an outer member having its inner surface tapered in a direction complementary to that of the taper ot' the inner member, and provided with an annular flange, a spline litting a groove formed between the n'ieeting tapered surfaces ol' said yinner and outer members,fa clamping ring fitted upon said outer member, and an internally threaded ring fitting upon the threaded end ol' said inner member, and bearing against the adjacent end of said outer member.

Signed by me, this 22 day ol' August 1906.

ALFREDI'A. DE' MARS.
